batman equation in advanced graph app

[Gabriel]

As you can see, even the single parts are wrong! The green part in the picture you posted shouldnt have the vertical and horizontal segments, and the violet one should be much shorter! In function app you can get correct plots except for the first part which isnt a y=f(x) so it can't be handled by the function app . I can't understand why the advanced graph app can't handle it (nor it can handle the complete equation) while it can handle the equations of the plot gallery(which are many lines long and are disequations!)
